My present improvements comprise means for controlling the boreblock of the roll of paper and regulating the bore. diameter with relation 'to the diameter of the retainingpin 21. The preferred construction for this puipose embodies V a ferrule, 2 8, .constituting a tubular collar whicliisl slidably mounted upon, the retaining pin, beneath the socket member 17, and has itscircumferential surfacetapered downwardly,-as at 29, which ferrulerorcollar enters the ,OP of the bore-blook'andaserves-.5 -to1 reduce, the bore thereof in krelation to the retaining pin ,and 'thus adapt the,- varying diameter or sizes of the bore in diterent'rolls of paper to the uniform jdiameterf or ksize A of the retaining pinf`21. Supplementary'to said bore-regulating meansa coiled'spring, 30, ismounted'up'on theiretainingpiii and tensionallyacts between the .bottom othe tubular body 24 of the socket-piece ,17-'and i the top ofthe ferrule or collar 28,*sa`id spring thus servingnot only toretain the bore- 'regulating erru'le within the bore-'block of the roll of paper but also to hold the boreblock downwardly in normali position withf in thepaper roll and precludeanyfteiid'ency latter,"above-` its taper surface, is preferably tpsaid block; to ride upwardlyon the retaining pin 21, whichA tendencyis'dueto Vfriction whenw the froll of' paper is turning under conditions' ofv use.vr The coiled' spring" 30 is preferably carried by-the regulating 'fer-rk rule :and for this purposethe top end of. the

provided with a "'circumferential'Y` shoulder, 31, above'which formed a circumferential groove or recess', .32,1 receiving the end'fof the spring, 30, :wherebythe spring" embraces said groove and is thusconnected to the ferruie i f i AThe retaining provenients,'isprovided 'atits top', above the Ysocket-piece 1'7, with'a revolving base or plate, 33, which preferably has a; ball bearing. In

the` preferred construction ,5 saidl bally bearing is 'constituted anv annular cup, Y34, which may befstamped from. sheet in-etal, mounted at the vtop end of'fthe 'retaining' -p'in "21,v and having a downwardly-extending body flange,

35, entering and secured .within the '.top end of the retaining pin, "the lattervfb'eing in' this preferred .construction preferably tubular. Saidballcup carries asetmof balls, 36,' upon which the yrevolving base `or' plate 33 rests `Vand bears, and said revolving base carries an axialpin, 3,7, extending.'downwardlyfrom its -under side andwithin the ball-cup member.

Saidy axial pin is alsoV projective' above the j 'revolving base 33 as' atl` 38,V andv turns therewith and is tubular. lTo retain the revolving base-plate upon its ball bearing and to prefvent upward movement ofsaid base, a `lock- "pin, 37, is insertedlongitudinally through pin 21, iiimy-*present iin-- the tubular axial pin `37, and is headed at itstop, as at 40, above the top extension 38 of the pin 37, and also headed or shouldered at its bottoni, as at 41, in connection with the ball-cup x member, said stationary lock-pin 39 thus constituting a vertical spindle upon which Vthe axial pin 37k of the revolving base 33 turns.A s ,The top revolving base 33 serves as a twine .holder and is adaptedtosupport ai'idcarry cones or spools of twine,"as indicated at 42,

otvaryinghsizes To-enable the detachable cutter device and away from the general operative and paper-cutting mechanism. In the" preferred construction, said bracket, 44, is carriedby the'ho'rizontal top portion orA arm 27 of the main standard orV upright V16, and-consists of; a` right angular ,strip or plateforming a vvertical yarm, 46,

in parallel relationship to tlierspool of twine, and a horizontal arm, 47, projecting rearn wardly therefrom, the terminalends of each of said arms havingatubular eyepiece, 48, the 'bores of which are in aplane diagonal to the vertical plane'of the revolvingV ball fof twine, whereby the tree end of the twine lfeeds through said eye-pieces downwardly and rearwardly and -is guided away from the'general operative mechanism of the de'- vice.L The twine guide-bracket'is secured in positionv preferablyby means `of a Uv-plate, 49,'icarried by its `horizontal arm y47V and downwardly embracing the topvarm 27 of the standard 16 andl clamped thereon by a cross-pin or screw, 50, passing through the guide' ientv and suitable position atthe rear ofthe )ends of the Uplate beneath said'standardf armv 27.
